FAQ – Radioactive Age-Dating

You go from changing their diapers, to teaching them how to tie their shoes, to eventually helping them understand dating and love. As hormones fly, you can expect to deal with your fair share of conflict. So when it comes to dating, how can you prepare yourself to deal with potential questions and issues? And what age is appropriate? The American Academy of Pediatrics notes that on average, girls begin dating as early as 12 and a half years old, and boys a year older. At this age, it probably means your son or daughter is sitting next to a special someone at lunch or hanging out at recess. Groups play a big role in relaying information about who likes whom.

The youngest dating age?

Facebook Messenger Gay dating culture can be quite difficult to navigate. While some have been fortunate enough to be in fruitful and lasting relationships, others struggle to find longer term partners. We recently saw a conversation about age surface on social media when media personality Somizi Mhlongo revealed that he was dating someone almost twice as young as him.

Is ageism an issue within the gay community? Mambaonline spoke to young people to find out if age matters or should matter in gay relationships. They should test the relationship dynamics.

Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

These are often characterised as the norm, rather than the exception. I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists. Geochronologists do not claim that radiometric dating is foolproof no scientific method is , but it does work reliably for most samples.

It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for “young Earth” theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques. This document is partly based on a prior posting composed in reply to Ted Holden. My thanks to both him and other critics for motivating me. Background Stratigraphic Principles and Relative Time Much of the Earth’s geology consists of successional layers of different rock types, piled one on top of another.

These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages. Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried.

As a result, glauconite is used for dating only with extreme caution. The ages from the Coast Range batholith in Alaska Table 2 are referenced by Woodmorappe to a report by Lanphere and others

According to some, you can determine your appropriate dating age range by only dating someone who is within a fifth of your own age. A fifth of a 20 year old’s age would be four years, for example, so they could date someone between 16 and 24 (four years older or younger).

Determining the age of surfaces on Mars Mike Caplinger, Malin Space Science Systems February A fundamental problem in planetary science is determining how the surface of a planet has changed over time. This tells us something about the dynamics of planetary interiors for example, how often volcanoes erupt or how often earthquakes occur and also something about the processes that affect planets from without for example, how likely it is that a giant asteroid might hit the Earth and change it radically.

The simplest way of describing how a surface has changed over time is to describe the age of each part of that surface. For example, one could make a map of the surface, color-coding it such that each color represents a different range of ages. But how are we to determine the age of a surface? On the Earth, we have easy access to the surface, and often, to many other older surfaces buried beneath it.

Obviously, if one surface has buried another, the deeper surface must be older. In the Grand Canyon, for example, one can see the various layers of rock that have been excavated on the canyon walls, and see the evolution of the surface in the area directly. The process of dating surfaces by looking at the relationships between them is called stratigraphy.

Radiometric Dating and the Geological Time Scale

July 2nd, by Nick Notas 97 Comments Half-your-age-plus-seven. This formula has somehow become the definitive rule for the youngest age of a woman a man can date. So a year old guy can date a year old girl. But many people in society still look down upon older men dating younger girls. This taboo makes some of my clients feel shameful about their age preferences.

A study finds boys and girls who start dating at a young age may have more school and behavioral problems than their peers.

How do scientists find the age of planets date samples or planetary time relative age and absolute age? We have rocks from the Moon brought back , meteorites, and rocks that we know came from Mars. We can then use radioactive age dating in order to date the ages of the surfaces when the rocks first formed, i. We also have meteorites from asteroids and can date them, too. These are the surfaces that we can get absolute ages for. For the others, one can only use relative age dating such as counting craters in order to estimate the age of the surface and the history of the surface.

The biggest assumption is that, to first order, the number of asteroids and comets hitting the Earth and the Moon was the same as for Mercury, Venus, and Mars. There is a lot of evidence that this is true. The bottom line is that the more craters one sees, the older the surface is. Why is it important to establish the age of a planet? This can be interpreted in two ways:

How old is old enough for kindergarten in ? Who decides the answer for kids today? Last year, a kindergarten-teacher friend and I were talking about the opening days of school. She was excited, and exhausted, and very eager to meet the challenges of the new school year when she said of her new class of kindergartners, “I forget how young they are in September.

Parents all over the country have been wiping their brows and many have been thinking, “Is Sara really old enough for kindergarten?

Within this calendar, a standard year consists of days with a leap day being introduced to the month of February during a leap year. The months of April, June, September, and November have 30 days, while the rest have 31 days except for February, which has 28 days in a standard year, and 29 in a leap year. The Gregorian calendar is a reformed version of the Julian calendar, which was itself a modification of the ancient Roman calendar.

The ancient Roman calendar was believed to be an observational lunar calendar, based on the cycles of the moon’s phases. The Romans were then believed to have adopted a month calendar with days, leaving the remaining 50 or so days as an unorganized winter. This calendar allowed summer and winter months to become completely misplaced, leading to the adoption of more accurate calendars.

The Republican calendar later used by Rome followed Greek calendars in its assumptions of From this point, many attempts were made to align the Republican calendar with the solar year including the addition of an extra month to certain years to supplant the lack of days in a particular year. In 46 BC, the calendar was further reformed by Julius Caesar, introducing an algorithm that removed the dependence of calendars from the observation of the new moon.

Calculators

Ads How does this age difference calculator work? This is a quick calculator that allows you to compute the age difference in a relationship or between any two people. It simply generates the ages of the two subjects according to the birth dates you input in the form and once you press Calculate it delivers the result. Please note that there is no importance on the order the two dates of birth are specified as the age difference calculator makes the absolute difference between the chronological age in each case and specifies which person is older.

The results are exemplified in the section below. Apart from the age , there are several other aspects people tend to look at when trying to figure out whether a specific relationship has good prospects or not such as horoscope and numerology compatibility.

In SAS, date type variables contain the number of days between January 1, , and the date specified. To compute age using a date of birth and the current.

Brad I found an interesting article that proposes a math equation for suggesting the age of people you should be willing to date. I really thought it worked well at the lower age ranges but in the 40s things started to get a little excessive first for the upper limit and then later for the lower limit as well. For example, my dad happens to be 57 years old.

The equation given would suggest that his optimal dating range would be between With that in mind, I decided to try my hand at an equation by adding a hard cap to to both the upper and lower limit. The new equation created using excel is: The same concept is applied to the upper limit. This is just one section of the entire results and you can download the entire excel sheet here.

Again, you can see the original article that this discussed this idea in detail over at Insatiable Hee. As that article points out, you should date the person who makes you happy regardless of age and I made this chart out of interest for the topic, not as some kind of rule that I think should be followed without question.

The Rules on Age Differences for Dating Teens

Physical Geology Home 1. Distinguish between absolute and relative dating. Absolute dating involves a numerical age measurement in actual time units, like thousands or millions of years.

The age of the Earth is ± billion years ( × 10 9 years ± 1%). This age may represent the age of the Earth’s accretion, of core formation, or of the material from which the Earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

In SAS, how can I calculate age from the date-of-birth data? This content has been archived , and is no longer maintained by Indiana University. Resources linked from this page may no longer be available or reliable. In SAS, date type variables contain the number of days between January 1, , and the date specified. To compute age using a date of birth and the current date, use the following code: DATE returns the current date set in the computer.

To specify a particular day, use the MDY function as follows: The first part of the command, intck ‘month’,birthday,today , returns the number of times the first day of a month is passed between birthday and today. Finally, the corrected number of months is divided by 12 and rounded to produce the correct age.

Astronomy Many independent measurements have established that the Earth and the universe are billions of years old. Geologists have found annual layers in ice that are easily counted to multiple tens of thousands of years, and when combined with radio isotope dating, we find hundreds of thousands of years of ice layers. Using the known rate of change in radio-active elements radiometric dating , some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.

Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years.

The rule says 17 (half your age plus seven) but that does put you as a college age student dating a high schooler (under most circumstances) which is kind of creepy. And in some states the age of consent is 18 (for others its 16 or 17) so in that case it would also be illegal.

But what about age? And what about age as it relates to older women involved with younger men? Actress Robin Wright, 47, is engaged to fellow actor Ben Foster, Pop star Shakira is involved with a man 10 years her junior. She is 13 years older than her mate. A recent article in Oprah magazine looked at a handful of real-life May-December romances, focusing mainly on those between older women and younger men.

Questions related to aging cropped up, naturally. Couples in this situation had to address the fertility concern head-on, with some choosing to take the leap relatively quickly while others took a pass. One woman, who is married to a man 14 years younger, said the only time she feels threatened by her age is when she looks in the mirror.
